I recently bought a 1987 Yamaha fz700, and the owner said the headlights didn't work, and I can't figure out what's wrong. We checked some of the wiring out, and the bulb connectors have no power going into them, on the high, or low beam setting. Also the high beam light doesn't light up on the dash when its in high beam mode. Another thing that we can't seem to get working is the turn signals. When they are slides either way, the turn light doesn't light up on the dash, and no power seems to be going to any of the cables in the back. The rear brake light works, but only when the foot brake lever is pressed, not the handlebar one. Fuses were checked and replaced, what else could be wrong? Could it just be some bad wiring from the previous owner?
Edit: There were some extra wires hanging around disconnected in the front of the bike, and when we measured them they were getting about 11v constant voltage, didn't matter if the high/low or turn signals were on.
I'm new to working with motorcycles, but I've had years of experience in wiring, and electronic systems, so I know a few things, but any help, or wiring diagrams could be nice! Thanks
